Among 29 CPAP-adherent men with severe obstructive sleep apnea, residual objective sleepiness was associated with white-matter diffusion differences, although the cross-sectional findings do not establish causality or support routine imaging.

Experts reviewing available evidence suggest melatonin and magnesium may support sleep through different mechanisms, though benefits appear dependent on the underlying cause of sleep disturbance and overall evidence remains mixed, particularly for magnesium.

A Florida senior care organization reported identifying more dementia cases at earlier stages after replacing paper-based cognitive screening with a brief digital assessment, though independent diagnostic validation remains unavailable.

Frontal tau accumulation was associated with disrupted deep-sleep slow waves and poorer episodic memory performance in older adults, offering a potential physiological link between Alzheimer’s-related pathology and age-related memory decline.

A systematic review of 30 longitudinal MRI studies found that CPAP therapy in obstructive sleep apnea (OSA) may be associated with structural, functional, vascular, and metabolic brain changes. However, the evidence remains heterogeneous, largely exploratory, and insufficient to support routine MRI monitoring of treatment response.

A systematic review and meta-analysis of studies involving more than 230,000 adolescents found that greater social jet lag was associated with higher anxiety levels. The findings identified a consistent but small association and did not establish causality.
